ODE SWS: a framework for designing and composing semantic Web services

Specifying semantic Web services requires designing the semantic description at a conceptual level to guarantee its correctness and avoid inconsistencies. We present a framework for designing and composing semantic Web services at the knowledge level in a language-independent manner. We base our framework on a stack of ontologies that explicitly describes different semantic Web services features, and on the assumption that the semantic Web services are modeled as problem-solving methods (PSMs) that describe the service´s internal structure.
